The font is LexiaDaMa in bold, I love the font and it's about the only one I use now on my reader. My eyes are bad as it is, but reading outdoors while I'm out and well past normal daylight, or on public transportation in the wrong seat, the font lets me keep reading in dimmer situations when I'd otherwise have needed a light.

And Registered Architect is a good choice too. It's just one of those things that you can't say what the author meant with 100% certainty that bugs me not knowing the common terms of the day back then.
